Abstract

Introduction: Post-extraction bleeding, which is difficult to stop, is rare. However, arterial hemorrhage may lead to a state in which hemostasis is difficult to obtain. We herein report a case in which arterial embolization effectively stopped hemorrhagic bleeding due to mandibular third molar extraction.

Case Report: The patient was a 24-year-old man who suffered from abnormal bleeding during left mandibular third molar extraction (tooth no. 48). As hemostasis via compression with gauze would be difficult, the patient was referred to our department for emergency treatment to stop the bleeding. There was nothing special to note in terms of his vital signs at the time of his initial visit, with pulsatile bleeding from the extraction socket of the left mandible. A panoramic radiograph showed the root of tooth no. 48 was suitably separated. On the day of his visit, hemostasis was performed via compression using tie-over gauze. No significant bleeding was observed after the removal. However, the patient visited the emergency department with a complaint of re-bleeding, and arterial bleeding from the extraction socket was observed upon the release of compression with gauze. A traumatic pseudoaneurysm consistent with the site of tooth extraction was observed by a selective angiographic examination during hospitalization. Hemostatic treatment with transcatheter arterial embolization (TAE) was performed at the Department of Diagnostic Radiology. The course was favorable following treatment on the seventh day after extraction, and the patient was discharged from the hospital in remission.
